Jessica Simpson's Baby Bash

Surrounded by 75 friends and relatives, a beaming Jessica Simpson strikes a stylish pose during her March 18 Charlotte’s Web–themed shower. “I feel like I could pop at any second,” Simpson, whose daughter Maxwell Drew arrived May 1, told PEOPLE. “I had a great pregnancy.”

“We’ve always been close, but when you start to have babies it makes you that much closer,” the fashion designer, 31, recently revealed about her bond with sister Ashlee, who brought along son Bronx, 3, to the party. “I’m glad our babies are just three years apart!”

Simpson’s proud mother, Tina, flashes a smile as she lovingly holds her eldest daughter’s belly. “I really hope I can be half as good of a mom as she is,” the singer said. “Your friendship as mother and daughter is more important than anything.”

Lots of Simpson’s celeb friends joined in on the festivities helmed by party planner Mindy Weiss, including Jessica Alba and 7-month-old daughter Haven, who indulged in Southern treats like fried chicken and mac and cheese. Actress Odette Annable and close pal CaCee Cobb also participated in games and knitting lessons. “To have all these people that already love her so much, I think that’s the biggest thing that makes me most happy right now,” Simpson said.

Gearing up for the arrival of their daughter, Simpson’s NFL player fiancé Eric Johnson proudly displays one of the couple’s many presents. “Eric is going to be an unbelievable dad,” she said. “I can’t wait to see if he can master ponytails and braids!”

A Fashion Star in the making? Looks like the designer’s bundle of joy may inherit her mom’s love for heels – the mini trendsetter-in-training was gifted 25 pairs of shoes.

As the fête comes to an end, the first-time parents goof around with a stuffed rabbit. “He’s going to be in a house full of girls, which is hilarious,” Simpson said about Johnson’s upcoming daddy duties. “It’s a good thing he’s a very patient person!”
